Pinterest is one of the fastest-growing websites in history, but it struggled for a long time.

Pinterest’s CEO recently said that it had “catastrophically small numbers” in its first year after launch and that if he had listened to popular startup advice he probably would have quit.

Pinterest eventually became successful, even though I am personally still stumped by it.

Of course, for every successful Pinterest, I am sure there are a thousand other attempts that were just as good, but never made it, for one reason or another.

Nothing is successful overnight. When you look behind the curtain, there is always hard work, perseverance and a good dose of luck involved.
